well the problem consists in the following. If the external stylesheet looks like
body { background-color: #000000; }
.content {
background-color: #FFFFFF;
color: #000000
}
then the editing window would be black text on a black background, but it would look ok with the presenting template.
The thing is that the external stylesheet is also being edited dynamically, so I have know control over it.
I don't know how to present the problem clearer than this. Hopefully you see the problem - or perhaps others have the same problem.
